An opto-mechanical module, including a light valve, and first and second prisms is provided. The light valve and the first prism are disposed on a transmission path of the illumination beam. The second prism is disposed on transmission paths of the illumination and image beams, and located between the light valve and the first prism. The first prism does not overlap with the light valve in an extension direction of the reflection surface parallel to the light valve. The illumination beam does not pass through an optical element or a fixing glue on a transmission path between the first and second prisms. The shortest distance from an intersection point of the illumination beam entering the first prism to the light valve is smaller than that from an intersection point of the image beam exiting the second prism to the light valve. A projection device including the opto-mechanical module is provided.

A folded camera that includes two light folding elements such as prisms and an independent lens system, located between the two prisms, which includes an aperture stop and a lens stack. The lens system may be moved on one or more axes independently of the prisms to provide autofocus and/or optical image stabilization for the camera. The shapes, materials, and arrangements of the refractive lens elements in the lens stack may be selected to capture high resolution, high quality images while providing a sufficiently long back focal length to accommodate the second prism.

An optical prism mounting system is described that includes a prism having a flexible insertion tab system. Also described, is a prism holder having an insertion channel, and a method of mounting the prism in a tonometer. The flexible insertion tab system includes a spring tab and a bendable tab; the spring tab is flexed as the prism moves along the channel; the flexible insertion tab system connects with the prism holder and snaps into a locked position at the end of the channel; and the prism and the prism holder can be separated after use by disengaging the flexible insertion tab system. An optical operating range of the optical prism is from about 0 ADC to about 600 ADC, and the maximum time for setting the tonometer is not more than about 150 seconds.

The present invention relates to a camera and a terminal comprising same. A camera and a terminal comprising same according to an embodiment of the present invention comprise: a lens device including a micromirror array; and a processor for outputting, to the micromirror array in the lens device, a curvature control signal for curvature change, wherein the micromirror array includes a plurality of micromirrors including a first micromirror and a second micromirror, and the second micromirror is closer to the outer periphery thereof than the first micromirror and has a larger tilting angle according to the control signal than the first micromirror. Accordingly, focus can be changed using the micromirror array.

An actuator for driving a reflector includes a movement frame, a first support frame, a first drive coil, a first rotation guide and a first ball. The movement frame includes a reflector configured to reflect or refract light to a lens and a first magnet. The first support frame is configured to provide a space of the movement frame to move. The first drive coil is configured to generate an electromagnetic force in the first magnet to rotationally move the movement frame in a first direction based on the first support frame. The first rotation guide is arranged between the movement frame and the first support frame and has an arc shape so that the movement frame rotates in the first direction. The first ball is arranged inside the first rotation guide, wherein a center of curvature of the first rotation guide corresponds to a center of rotation of the reflector.

An optical path turning module includes an optical path turning unit, a carrier, a fixing element and a driver. The optical path turning unit includes a sloping surface. A light beam enters the optical path turning unit along a first axis, is reflected by the sloping surface, and leaves the optical path turning unit along a second axis. The carrier is configured to fix the optical path turning unit and includes a main body and a plurality of first clamping portions. The main body is sloped with respect to the second axis, and the first clamping portions extend from the main body in a direction parallel to the second axis.
